Chthoniobacter flavus Ellin428 is the first isolate from the class Spartobacteria of the bacterial phylum Verrucomicrobia. C. flavus Ellin428 can metabolize many of the saccharide components of plant biomass but is incapable of growth on amino acids or organic acids other than pyruvate. [Read More]

“Pedosphaera parvula” Ellin514 is an aerobically grown verrucomicrobial isolate from pasture soil. It is one of the few cultured representatives of subdivision 3 of the phylum Verrucomicrobia. Members of this group are widespread in terrestrial environments. [Read More]

Carboxysomes are metabolic modules for CO(2) fixation that are found in all cyanobacteria and some chemoautotrophic bacteria. They comprise a semi-permeable proteinaceous shell that encapsulates ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase. Structural studies are revealing the integral role of the shell protein paralogs to carboxysome form and function. The shell proteins are composed of two… [Read More]

‘Thermobaculum terrenum’ Botero et al. 2004 is the sole species within the proposed genus ‘Thermobaculum’. Strain YNP1(T) is the only cultivated member of an acid tolerant, extremely thermophilic species belonging to a phylogenetically isolated environmental clone group within the phylum Chloroflexi. At present, the name ‘Thermobaculum terrenum’ is not yet validly published as it contravenes… [Read More]

Bacillus tusciae Bonjour & Aragno 1994 is a hydrogen-oxidizing, thermoacidophilic spore former that lives as a facultative chemolithoautotroph in solfataras. Although 16S rRNA gene sequencing was well established at the time of the initial description of the organism, 16S sequence data were not available and the strain was placed into the genus Bacillus based on… [Read More]
